Natural populations of Dichroplus elongatus often exhibit diverse forms of supernumerary heterochromatin. In Tafi Viejo, Tucumán (Argentina), parallel polymorphisms for extra segments on pairs M6, S9 (proximal) and S10 (distal) and a mitotically unstable B chromosome were detected. The segments produce intrachromosome effects excluding chiasmata from their neigbourhood and displacing them to regions distal to the extra heterochromatin. The individuals bearing simultaneously the B and the… Expand

Supernumerary Chromosome Variants in Dichroplus elongatus (Acrididae): Fluorescent Banding and Cline Variation Pattern
TLDR
Dichroplus elongatus is a South American grasshopper that shows simultaneous polymorphisms for B chromosomes and several supernumerary segments located in chromosome pairs S10, S9, and M6, in natural populations from Argentina, and the pattern of chromosome variation is discussed in relation to the population's ability to maintain supern numerical DNA in more climatically favorable geographic regions. Expand
Non Random Distribution Patterns of Supernumerary Segments and B Chromosomes in Dichroplus Elongates (Orthoptera)
TLDR
The patterns of chromosome variation do not agree with the geographical distribution of the populations, and the covariation of the heterochromatic forms may act as another factor that establish limits to stochastic factors, and could be involved in the non random pattern detected in D. elongarus. Expand
Interaction among different heterocromatic variants in the grasshopper Dichroplus elongatus.
TLDR
The present results point out the importance of the interaction among heterochromatic variants in the chromosome intraspecific variation in east Argentina natural populations of the grasshopper D. elongatus. Expand
Mitotically unstable B chromosome polymorphism in the grasshopper Dichroplus elongatus
TLDR
The probable influence on fertility of carriers considering the production of abnormal sperm formation in relation to the number of Bs per follicle was discussed and it was suggested that the pattern of B chromosomes may not be explained by historical factors. Expand
On the origin of B-chromosomes: neo XY systems and X-like supernumeraries in Orthoptera
TLDR
It is pointed out that small Bs could originate from polysomy of the smallest chromosomes, tolerated because of the few genes involved in Cylindrotettix obscurus, and the minute-B category is attributed to residua... Expand
Post-meiotic B chromosome expulsion, during spermiogenesis, in two grasshopper species
TLDR
It is shown for the first time that most microspermatids formed during spermiogenesis in two grasshopper species contain expulsed B chromosomes, concluding that B chromosome elimination during s permiogenesis is a defense weapon of the host genome to get rid of parasitic chromosomes. Expand
Effects of B chromosomes and supernumerary segments on morphometric traits and adult fitness components in the grasshopper, Dichroplus elongatus (Acrididae)
TLDR
The uni‐ and multivariate analysis of mating success revealed that sexual selection favours larger individuals of both sexes and males with standard karyotype, and suggested that B chromosome carrying females have higher numbers of embryos per clutch and ovarioles per ovary. Expand
Effects of Phenotype and B-Chromosomes on Adult Survival in Dichroplus elongatus (Orthoptera: Acrididae)
TLDR
The results suggest that B-chromosomes cause detrimental effects on body-size related traits that are selected for adult male survival, and the hypothesis that their persistence in Argentinean populations depends on trade-offs between opposite selective effects is supported. Expand
The odd-even effect in mitotically unstable B chromosomes in grasshoppers
TLDR
Some features of meiotic behaviour in known cases of polysomy and mitotically unstable Bs in grasshoppers are reviewed, in looking for possible causes for the odd-even effect. Expand

Effects of supernumerary heterochromatin on chiasma condition in two species of Acrididae (Orthoptera)
TLDR
A supernumerary terminal segment in S10 pair was observed in a heterozygous condition in several individuals of D. elongatus and has an intrachromosomal effect since it modifies the location of chiasmata in the bivalent involved. Expand
Meiotic effects of supernumerary heterochromatin in Heteropternis obscurella
The endemic Australian grasshopper Heteropternis obscurella shows considerable variation in respect of both chromosome structure and chromosome behaviour. The structural differences depend uponExpand
Meiotic Behaviour and Dosage Effect of B-Chromosomes on Recombination in Dichroplus Elongatus (Orthoptera: Acrididae)
TLDR
A detailed analysis of four B carrying individuals from the same population is reported, finding that univalents or terminally associated B bivalents could persist even to first anaphase migrating undivided to the same pole. Expand
The supernumerary segment system of Stethophyma
TLDR
It is proposed that interstitially located supernumerary segments may prove to be more common than has previously been accepted and that the rod chromosomes of many Acridids may well be telocentric as in the case under study. Expand
Meiotic Behaviour in a Population of Dichroplus Elongatus (Orthoptera: Acrididae)
TLDR
Comparisons indicated that terminalization in this species is limited to diplotene and B's have no effect on the mean number of chiasmata per cell but tend to increase the between cell variance. Expand
A cytogenetic analysis in Psophus stridulus (L.) (Orthoptera: Acrididae): B-chromosomes and abnormal spermatid nuclei
TLDR
The male chromosome complement of Psophus stridulus (L.) (Orthoptera: Acrididae) has been analyzed by using orcein staining, C-banding and silver impregnation, and meiotic behaviour indicates that it is an isochromosome. Expand
The supernumerary segment system of Stethophyma
TLDR
The variation in segment structure and the distribution of standard heterochromatin, among the European species of S. grossum suggests that these systems have evolved independently in different populations. Expand
C-Heterochromatin content of supernumerary chromosome segments of grasshoppers: Detection of an euchromatic extra segment
TLDR
A unique euchromatic supernumerary segment was present in the five populations of Omocestus bolivari analysed, which appears negatively heteropyenotic during the first prophase of meiosis and does not C-band. Expand

TLDR
A population of the grasshopper Calliptamus palaestinensisBdhr from near Jerusalem, Israel was analyzed cytologically and it was suggested that variation due to non-disjunction would be maintained only in association with accumulation mechanisms. Expand
Influence of a rare unstable B-chromosome on chiasma frequency and nonhaploid sperm production in Dichroplus pratensis (Melanoplinae, Acrididae)
TLDR
Three B-containing individuals of Dichroplus pratensis were found among 300 males collected in several Argentine localities and the presence of Bs increased the production rate of abnormal spermatids and chiasma frequency and between-cell variance were increased in B- containing cells. Expand
